In one implementation, the apparatus includes an elongate member, an electrode carrier and one or more conductors. The elongate member has a lumen operable to couple to a vacuum source and draw moisture way from one or more electrodes included in the electrode carrier, and a lumen configured to receive a hysteroscope. The electrode carrier includes one or more bipolar electrodes and can to couple to a radio frequency energy generator. The one or more conductors connect to a controller operable to control the delivery of radio frequency energy to the one or more bipolar electrodes. The elongate member is a substantially rigid member configured with a curve to facilitate advancement of the distal end transcervically through a uterus and into a region of a tubal ostium of a fallopian tube to be occluded.

Abstract: A uterine length measurement device includes a first elongate member having a distal end, a proximal end, and a lumen, the elongate member configured for insertion into an endocervical canal where the distal end is configured for insertion to approximately an internal cervical os of the endocervical canal. A second elongate member is provided having a distal end and a proximal end, the second elongate member configured to move within the lumen of the first elongate member, where the distal end can protrude from the distal end of the first elongate member and is configured for insertion to approximately the fundus of a uterine cavity. Moving the second elongate member relative to the first elongate member to position the distal end of the second elongate member at approximately the fundus of the uterus provides a direct measurement of a length of the uterine cavity.

Abstract: Lung volume reduction is performed in a minimally invasive manner by isolating a lung tissue segment, optionally reducing gas flow obstructions within the segment, and aspirating the segment to cause the segment to at least partially collapse. Further optionally, external pressure may be applied on the segment to assist in complete collapse. Reduction of gas flow obstructions may be achieved in a variety of ways, including over inflation of the lung, introduction of mucolytic or dilation agents, application of vibrational energy, induction of absorption atelectasis, or the like. Optionally, diagnostic procedures on the isolated lung segment may be performed, typically using the same isolation/access catheter.

Abstract: A system and method for marking a tissue site are described. A marker is deployed into or near the tissue site, where the marker can be later located using an imaging device external to the patient's body. After withdrawing the internal imaging device, the location of the marker can be identified using an external imaging device. Optionally, a biopsy of the internal tissue site can be performed based on the location of the marker.

Abstract: Methods, systems and devices are provided for performing lung volume reduction in patients suffering from chronic obstructive pulmonary disease or other conditions where isolation of a lung segment or reduction of lung volume is desired. The methods are minimally invasive with instruments being introduced through the mouth (endotracheally) and rely on isolating the target lung tissue segment from other regions of the lung and occluding various lung passageways with the use of occlusal stents. The occlusal stents are delivered with the use of an occlusal stent delivery system which is loaded with the occlusal stent with the use of an occlusal stent loading system.

Abstract: Improved methods, systems and devices for occluding body passageways, particularly lung passageways. Such occlusion is achieved with occlusal stents which are particularly suited for use in performing Endobronchial Volume Reduction (EVR) in patients suffering from chronic obstructive pulmonary disease or other conditions where isolation of a lung segment or reduction of lung volume is desired. The present invention is likewise suitable for the treatment of bronchopleural fistula and potentially for other pulmonary diseases, such as hemoptysis and pneumothorax. The occlusal stents are delivered with the use of any suitable delivery system, particularly minimally invasive with instruments introduced through the mouth (endotracheally). A target lung tissue segment is isolated from other regions of the lung by deploying an occlusal stent into a target area of a lung passageway. A variety of different occlusal stent designs are provided to improve the performance and reliability of the delivered occlusal stent.

Abstract: The present invention provides improved methods, systems, devices and kits for performing lung volume reduction in patients suffering from chronic obstructive pulmonary disease or other conditions where isolation of a lung segment or reduction of lung volume is desired. The methods are minimally invasive with instruments being introduced through the mouth (endotracheally) and rely on isolating the target lung tissue segment from other regions of the lung. Isolation is achieved by deploying an obstructive device in a lung passageway leading to the target lung tissue segment. Once the obstructive device is anchored in place, the segment can be aspirated through the device. This may be achieved by a number of methods, including coupling an aspiration catheter to an inlet port on the obstruction device and aspirating through the port.

Abstract: Apparatus, methods, and kits, are provided for use in combination with a conventional bronchoscope or other lung viewing scope. In particular, sheaths having an inflatable cuff at their distal end are provided to receive a viewing scope through a lumen thereof. The sheaths thus provide an inflatable cuff on a viewing scope assembly so that the scope can be used in procedures which require selective isolation of regions of a patient's lungs. In particular embodiments, the sheaths may include stop elements for properly positioning a viewing scope therein, pressure transducers for providing accurate lung pressure information during procedures, and the like. Methods for using and forming sheaths having inflatable cuffs are also described.

Abstract: Devices and methods are provided for acquiring and analyzing an image data file to generate diagnostic information reflecting an individual lung compartment. A lung compartment could be an entire lobe, a segment or a subsegment and beyond, hereinafter subsegments and beyond will be referred to simply as segments. Such analysis is used to assess the level of disease of individual lung compartments, both for quantification of the disease state and for determining the most appropriate treatment plan. This analysis allows the imaging technology to be used as a functional diagnostic tool as well as an anatomical diagnostic tool. To this end, dynamic data or images may also be acquired at specific points throughout the breathing cycle. Since air movement in and out of a lung compartment during the breathing cycle is a direct indicator of lung function in some diseases like emphysema, analysis of images during the breathing cycle will indicate levels of disease.
